What is Deduplication and how does it work?

What is Deduplication and how does it work? Data deduplication (often called "intelligent compression" or "single-instance storage") is a method of reducing storage needs by eliminating redundant data. Only one unique instance of the data is actually retained on storage media, such as disk or tape. Redundant data is replaced with a pointer to the unique data copy. 

 File vs. Block Level Deduplication: Data deduplication can generally operate at the file, block, and even the bit level. File deduplication eliminates duplicate files. Block and bit deduplication looks within a file and saves unique iterations of each block or bit. Each chunk of data is processed using a hash algorithm. Backup Exec 2010 delivers “block level” deduplication thus providing a higher level of compression and storage savings over files level deduplication.
